Antifouling effect of green plants and plant configuration

Abstract The green anti-fouling effects, including reduction of harmful gas concentrations in the atmosphere, absorption lag dust, reducing air content of bacteria and radioactive substances, noise attenuation, improved micro-climate, etc., and proposed anti-pollution green plant species selection and configuration.

Keywords: plant green; pollution effects; species selection; Plants

Environmental pollution is the current world countries are facing serious problems, the rapid development of modern industry, so a lot of harmful gases, dust and other pollutants into the environment, far more than the self-purification ability of the environment, the entire eco-systems have been destroyed. green plants can be maintained oxygen, carbon dioxide balance, harmful gases, dust and noise absorption, block, filter effects, you can clean up the environment [1-2]. Therefore, a large number of polluting factories for producing enterprises, green building into an important part of environmental protection.

An anti-fouling effect of Greening
1.1 reduce atmospheric concentrations of toxic and hazardous gases
Large green trees, can absorb some of the harmful gases in the air, reducing the concentration of harmful gases in the air, such as: Euonymus japonicus, privet, oleander, acacia, Magnolia grandiflora and other strong resistance to sulfur dioxide; privet , Paulownia, Robinia pseudoacacia, E. japonicus and others have a strong ability of absorbing fluoride; structure tree, Acacia, Bauhinia, hibiscus has a strong anti-chlorine, chlorine absorption capacity. It is the determination of a 5 m wide with a suspended wood Lin Shulin can reduce the concentration of sulfur dioxide more than 25%, plus Young, cinnamon willow can absorb aldehydes, ketones, ethers and other toxic gases. containing chlorine gas with the flow of air through the width of 15 m, high 7 m, canopy density of 0.7 to 0.8 of the jungle , the chlorine concentration decreased 59.1%; containing hydrogen fluoride air through the 20 m wide and broad-leaved forest, the hydrogen fluoride concentration of lower than 10% open area.

The absorption effects of dust 1.2
Green belt to reduce the amount of atmospheric dust and particulates by the amount of effect is very significant. According to the determination of the year the amount of green space in the dust are lower than industrial park, commercial and living areas. A green belt block lots, open space than the non-forest area reduced 23% dust 52%, particulates by 37% to 60% reduction in dust and grass effects are more significant. It is measured when the wind speed is 4, in the grass covered lots, the air particulates were not detected; few trees, no grass lots, particulates up to 0.77 mg/m3, on the ground completely bare, trees are scarce lot, particulates up to 9 mg/m3.

1.3 The reduction of air content of bacteria and radioactive substances
Trees reduce the dust and the trees themselves the role of the secretion of spinosad, the green bacteria in the air greatly reduced, such as the sycamore leaf crumple, they would kill the protozoa within the 3 min. Green areas in cities compared with non-green street ratio, reduced the bacterial content of the air more than 85%. trees absorb radioactive substances, filtration, thereby reducing the content of radioactive substances in the air. tests showed that the forest can reduce the invasion of radioactive substances 30% to 60%, thereby reducing the radiation transmission.

1.4 noise attenuation, to improve the small environment and climate
Green plants have on the acoustic scattering, absorption, hedges, green walls for the sound source and receiver points in its height within the barrier and absorb the noise effect is very significant. Experiment showed that when the noise from the two lines through the pine and cedar form a line of 18 m wide belt, the noise reduced 16 dB, 36 m wide belt through reduced after 30 dB. Meanwhile, the ratio of broad-leaved evergreen broadleaf trees, with leaves leaves no better than the noise reduction [3-4] .

Industrial Park Green in addition to reduce atmospheric pollution, while improving the micro-climate has a significant effect, it adjust the temperature, air temperature, air flow, solar radiation and so have a good effect. It measured the height of summer the woods under the temperature than the bare lower 3 ~ 5 �� . green in the summer can absorb 60% to 80% of solar energy, 90% of the radiation, the temperature decreased about 3 ��; park green relative humidity less than 27% in areas of high, trees can increase the relative humidity of 10% 20%.

2 factory stain green plant species selection and configuration
To improve the green plants, must be appropriate to select the tree, the tree selection for plants to ensure good growth of plants in order to achieve the purpose of improving the environment. Choose a good anti-fouling green plants, with the exception must be suitable for the local climate, soil conditions, must also be possible, the following conditions: First, strong ability of anti-air pollution, the best selection and type of resistance to several types of pollutants; the second is the ability to have clean air, especially with strong resistance and purification efficiency high; Third, strong adaptability and drought, cold, barren-resistant, anti-lag and to adapt to a wide range of soil pH; fourth is a better green, beautifying effect; five is easy cultivation and management, initiation ability [5 - 6].

Plant is the main source of air pollutants, green house plant layout, reduce the plant itself to the environment from pollution and the plant itself to the requirements of two air purification aspect of departure. Green plant configuration principle: According to the partition function of the plant area, rational distribution to maximize green space in improving the environment, health protection, protection of the production, the rest to create a comfortable environment and beautiful environment, the integrated production capabilities. the relative concentration of pollutants around the workshop, should be planted in dirt, pollution and strong absorption species, to the lawn, trees and shrubs form a certain level of space and three-dimensional barrier; office and living areas pollution is light, green building to meet the beauty of the landscape and the people close to the natural desire of the main groups should be configured trees, lawns , flower beds, hedges; in the plant street trees along the roadside for planting trees to form Network, forming the skeleton of green plants.

3 Conclusion
Industrial enterprises, gardens, and environmental protection departments should attach importance to industrial enterprises in green building, green building good industrial enterprises play in improving the environment and maintaining ecological balance and other aspects of an important role.
